I'm looking to book a flight using my BA miles before the changes occur on 11/16 but am having problems finding the best way to go about this. My home airport is BDL but I know I will have to fly out of JFK which is fine. I'm looking to do a South American trip with 2-3 stops. Any advise on possible routes and how to book would be much appreciated. As you know the BA website is very difficult to find rewards. I have about 75k miles.
